report

public void report(@NonNull
                   Issue issue,
                   @Nullable
                   org.w3c.dom.Node scope,

Reports an issue applicable to a given DOM node. The DOM node is used as the scope to check for suppress lint annotations.

Parameters:

issue - the issue to report

scope - the DOM node scope the error applies to. The lint infrastructure will check whether there are suppress directives on this node (or its enclosing nodes) and if so suppress the warning without involving the client.

location - the location of the issue, or null if not known

message - the message for this warning
